起升特性是塔式起重机的主要技术参数,确定得是否合理直接影响整机性能和结构成本。本文通过对动臂与平头塔机起升性能的对比分析,得出影响动臂塔机起升特性的关键因素,并对各组成关键因素进行分析,给出了降低头部重量的合理建议。通过对现有产品实例计算,得出了优化后的起升性能曲线,远端性能明显提升,具有一定的工程实用价值。
Lifting characteristics of the tower crane is the main technical parameters to determine whether a reasonable and direct impact on overall performance and structural costs. In this paper, through comparative analysis on the lifting performance of boom and flathead tower crane, the key factors that affect the lifting characteristics of the tower crane are obtained. The key factors of each tower crane are analyzed, and some reasonable suggestions to reduce the head weight are given. By calculating the existing product instances, the optimized lifting performance curve is obtained, and the remote performance is obviously improved, which has certain engineering practical value.
